This is a math activity that has students practice the concept of estimation. It is an outline of a bunny face. First students make an estimation as to how many marshmallows they can fit around the perimeter of the bunny face. Then glue marshmallows around the bunny face. Count the marshmallows used and write the actual number down. See if your estimation was pretty close, too high, or too low to the actual number used. This was used with kindergarten students.
